摘要： At the time of playing a disk (2), TOC information in a lead-in area will be read out first after loading of the disk (2) is complete. The player (1) determines whether the disk (2) to be played is an audio disk (CD) or a memory disk (CD-ROM) based on identifying information in the TOC information. If the disk (2) is the memory disk the operation goes directly to a pause mode so that upon reception of a read command transition to the searching for a designated address is promptly executed to quickly read out the desired data. Only when the disk (2) being played is the audio disk, the audio system is changed to the audio disk from another source, thus permitting a user to view a map while listening to the previous source. When playing for an area having a series of group information recorded is complete in special play mode, the mode is quickly changed to the pause mode in the case of the memory disk to wait for the read command, thus ensuring quick reading of designated map data. If the disk discrimination result indicates the memory disk a muting process is performed to inhibit a sound generation from a loudspaker. If in this case there are operation commands originating from erroneous confirmation by the user, at least one of the commands is ignored. Further, transimission of a digital signal acquired by an EFM demodulator (9) to a signal processor including a D/A converter (12) is cut off, thus preventing electirc power from being wastefully consumed in the D/A converter (12).

摘要： A method and system of deriving a travel distance of an object which travels, comprising the steps of:
measuring a forward travel velocity of the object under forward travel;
discriminating whether or not the measured forward travel velocity is greater than a preset specified velocity;
detecting a level of a backward travel signal indicative of a state of the object under backward travel, when the measured forward travel velocity is greater than the specified velocity; and
calculating the travel distance of the object independently of the travel distance of the object in a case that a level of the backward travel signal differs from the detected level.摘要翻译： 一种导出行进物体的行进距离的方法和系统，包括以下步骤：测量在向前行进中物体的向前行进速度; 判别所测量的前进行驶速度是否大于预设的规定速度; 当测得的前进速度大于规定速度时，检测表示后退时的物体的状态的后退信号的电平; 以及在后退行驶信号的电平与检测到的电平不同的情况下，独立于对象的行进距离计算对象的行进距离。

摘要翻译： 在播放盘（2）时，在完成盘（2）的装载之后，首先读出导入区中的TOC信息。 播放器（1）基于TOC信息中的识别信息确定要播放的盘（2）是音频盘（CD）还是存储盘（CD-ROM）。 如果磁盘（2）是存储盘，则操作直接进入暂停模式，使得在接收到读命令时，迅速地执行到寻找指定地址的转换，以快速读出所需数据。 只有当正在播放的磁盘（2）是音频盘时，音频系统才从另一个源改变为音频磁盘，从而允许用户在收听上一个源时查看地图。 当在特殊播放模式下完成具有一系列组信息的区域播放时，在存储盘的情况下，模式快速地改变为暂停模式以等待读命令，从而确保指定地图数据的快速读取 。 如果盘识别结果指示存储器盘执行静音处理以抑制从扬声器产生声音。 如果在这种情况下存在由用户的错误确认引起的操作命令，则忽略至少一个命令。 此外，由EFM解调器（9）获取的数字信号向包括D / A转换器（12）的信号处理器的转换被切断，从而防止在D / A转换器（12）中浪费地消耗电气功率。
